I am having a problem where my 2006 Jeep Grand Cherokee will not start consistently. When I turn the key, sometimes it starts, sometimes there is just a clicking noise. It wouldn't start at all one day. Two days later it started right up. Starter? Battery? Alternator? Other?
On an intermittent start problem like this you may be having a starter solenoid issue or your wire on the starter from the key switch may be loose. Or you may have a corroded battery cable or the safety neutral switch may be going bad. Is it a automatic? If it were it would be the clutch safety switch going out. So do the simple things first. Clean cables like the first guy said if that does not fix it locate the starter and if you have jumper cables the next time it does it put the positive lead of the jumper cable on the Positive battery terminal and the other touch to the starter wire with the key in the run position where the big wire on the starter is, if you here it spin it means the starter motor is ok if it don't it is bad or the connection on the starter is loose. Also a bad battery cable could cause this from the battery to the starter next put a small wire into the end of the positive jumper cable and touch the S terminal on the starter if you here a solid clung it means the solenoid is good. So check the connections on the starter and tighten the starter bolts as they may have worked loose and don't have a good ground. So if you want more as stance just post on my question and I will hell p more and if this is more informative please rate
It could be the starter solenoid, Ignition switch or the battery. Have the battery & alternator checked first. I believe Auto Zone will do it for free. They might even do a started draw test for free! If the battery and alternator are ok, Have the starter checked. It's much easier than checking or changing the ignition switch. Get a service manuel for the car it will be helpful. Good Luck!!
Check the battery terminals on the battery.These could be nasty and keeping the connection bad.When cleaning the cables make the battery post shiney,and the cable terminals shiney when you clean them.Clean the top of battery with soap and water.The acid on top of the battery can conduct electricity and cause the battery to drain down.If the battery cable and battery post are not shiney,they are not making the connection very good.+After you clean the post and the terminal ends,and the batery top,replace them back on the batery real good and tight ,then purchase ignition sealer at the auto parts store(NAPA carries this)and soak the battery terminals really good,and spray the top of the battery with the spray ignition sealer like you are painting it.This will keep the battery in good shape for a long time.
